I'm intrigued - you put a comment on a public forum, and then days later want to go back and change and/or delete it?

I guess this is simply a time to learn about what happens when you make comments in public. This, by the way, is why politicians never say anything interesting. There's no way to go back and change or delete it.

If you regret what you said, then say so. If you've changed your mind, then say so. the audience here is generally accepting of the fact that people change their mind. If done appropriately, it's a sign of strength.

Owning up to it even more so.
